Why do malignant tumors cause pain?

There are many reasons for this, first of all, it depends on the atypia of the malignant tumor, its nature, etc....In general, when a malignant tumor invades a nerve, it can cause pain....

The causes of cancer pain can be grouped into four categories:

1 Cancer infiltration and destruction caused by cancer itself, causing pain caused by damage to tissues and organs, accounting for about 85%. Pain caused by cancer is common in bone metastases, compression or infiltration of nerves, invasion of meninges and dura mater, invasion of internal organs, and invasion of **.

2 Cancer-related pain.

Pain in advanced cancer, such as constipation, bedsores and other lesions, can cause pain.

3 Anti-cancer**-related pain.

Mucositis caused by chemotherapy and radiotherapy, surgical trauma and scarring can all cause pain.

4 Pain not caused by cancer.

Cancer patients with certain pathologies, such as gout, arthritis, spondyloarthrotic anatomia, etc.

Pain in cancer patients can be caused by two or more causes.

Generally speaking, pain is a protective reflex of the human body, when the body is injured or a disease occurs, pain will occur in the relevant parts, so that the patient is alert, actively seek treatment, and avoid further damage to the body. The pain caused by a malignant tumor is very different from general pain and tends to be constant and severe. There are many causes of pain caused by malignant tumors, and it is generally believed that there are the following causes:

1) Tumors of solid organs grow rapidly, resulting in tension and traction of the organ capsule.

2) The tumor compresses the nerve root or nerve trunk, or occurs directly on the nerve trunk (e.g., schwannoma).

3) Advanced tumor infiltrates nerve trunks and plexus.

4) Obstruction of hollow organs (digestive tract and urinary tract) caused by tumors.

5) Bleeding and perforation caused by ruptured tumor of the digestive tract.

6) The tumor itself is ulcerated and infected, causing necrosis of the surrounding tissues.

7) Tumor infiltrates blood vessels, resulting in arterial occlusion, venous congestion, and local hypoxia can cause severe pain.

8) The tumor infiltrates into the lymphoid tissue, produces inflammation and releases a variety of chemical pain-causing substances.

9) Bone metastasis caused by fracture.

10) Scars from some surgeries, radiotherapy, and chemotherapy can also cause pain.

Pain can be exacerbated by worsening of the condition, a series of pathophysiological changes caused by malnutrition, and complex mental activity.

Enlarged tumor cells can compress nerves and cause pain.

Pain can be caused by nerve invasion or compression.

Even tumors will be painful, and it depends on medicine.

Just remember that most of the painful and movable ones that can be touched by the hand will not be malignant, but it is still necessary to make an incision for pathological examination.

Benign tumors depend on the part of the body where it grows, most of the tumors in vitro are painful due to the bump and friction, and the tumors in the body will not be painful if there is no squeezing around the organs, but there is always discomfort, benign tumors have pain, there are pain, there are painless, and there are a variety of symptoms that are not relieved.

Patients with intermediate and advanced malignant tumors often have painful symptoms. This pain is characterized by a long duration and progressive exacerbation, that is, the pain becomes more and more intense as the disease progresses. In the end, some patients develop abnormal pain, unbearable pain, and even think of suicide in extreme cases.

There are many causes of pain caused by tumors, which are generally related to the following factors:

l) Tumors of solid organs grow rapidly, resulting in tension and traction of the organ capsule.

2) The cancer compresses the nerve root or nerve trunk, or occurs directly on the nerve trunk (such as schwannoma).

3) Advanced cancer infiltrates nerve trunks and plexus.

4) Obstruction of hollow organs (digestive tract and urinary tract) caused by cancer.

5) Bleeding and perforation caused by ruptured tumor of the digestive tract.

6) The tumor itself is ulcerated and infected, causing necrosis of the surrounding tissues.

7) Cancer infiltrates blood vessels, and local hypoxia can cause drama.

Intense pain. 8) Radiation** sequelae.

Symptoms of pain due to the spread and development of divergent inflammation, the formation of fluid accumulation or the internal pressure generated after the increase in volume and the squeezing of the nerve. It can be conservative in the external application of traditional Chinese medicine preparations to help solve the problem.

First of all, it is certain that this person is greedy and does not know how to detox! From the analysis of the cancer word in Chinese, the side of the mouth indicates that the person is sick, and the three mouths inside indicate that this is from gluttony, and also represents the three mouths of the human body, which is the mouth, nose and the pores of the whole body. The following mountain character shows that the virus has accumulated like a mountain.

This cancer is formed!
